DUAPLATE

Duaplate® D80 is a chromium carbide weld overlay used in the Fixed Plant industry.

The manufacturing process of Duaplate®, along with the microstructure and chemical composition, give D80 its superior properties. D80 performs well under very high impact and very severe abrasive environments. Large sheets or custom shapes of Duaplate® D80 are available and can be formed into complex shapes.

The D80 overlay material is a complex chromium carbide weld overlay that is based on AS2576-2455. The microstructure of this material consists of primary M7C3 carbides in a complex carbide austenite matrix. The toughness of the material is improved by the formation of nodular complex carbides leading to a reduction in the size of acicular M7C3 type carbides and inter-carbide spacing.

Duaplate Manufacture

Duaplate® is manufactured by welding an abrasion resistant material to a mild steel base. A chromium rich powder is fused to the base plate, creating a bi-metallic material with high abrasion resistance whilst still retaining ductility allowing forming and welding. Multiple overlay and backing plate thickness options are available.
